Robotic and Aerospace Engineers Redesign McDonald's Drinking Straw

Adjust Comment Print

McDonald's new Chocolate Shamrock Shake presents food-mixer purists with a problem: There is a layer of mint and a layer of chocolate, and they need to be consumed together.

You read that right. That's a fifty-fifty combination of McDonald's standard chocolate milkshake with the minty seasonal Shamrock Shake.

Okay, it's a straw made specifically for the Chocolate Shamrock Shake, so that you can suck both flavors at the same time rather than switching between chocolate and mint.

Ivanka and Melania Trump will share 'the First Family Office'
The 35-year-old made her debut solo appearance as First Lady when she met the Japanese Prime Minister's wife. Melania Trump has signaled her intention to use her time in the spotlight to build her "brand".

This one goes out to all the Shamrock Shake Lovers.

Calling the assignment an "ambitious goal", principal engineer and managing partner at NK Labs Seth Newburg explained, "From a physics perspective, it's actually quite hard to deliver a proportional amount of both chocolate and mint flavors with each sip. It's a marvel of fluid dynamics", Seth Newburg, principal engineer and managing partner at NK Labs, said in a statement. But that's exactly what we did. The U-bend and the strategically places holes will allow for better flow and mixing of the shakes ingredients. There are two inlets on the extended U section and one big inlet at the bottom, at the curve of the straw. However at the end of the day, all the other straws are the same unlike the McDonald's new straw. Meanwhile, McDonald's has yet to put any engineers on the problem of fixing the Shamrock Shakes' persistent unusual chemical aftertaste. These included a Shamrock Chocolate Chip Frappe, a Chocolate Shamrock Shake, Shamrock Hot Chocolate, and a Shamrock Mocha. Let's hope the STRAW can also suction off those festive green sugar flakes on top!
